- the clone() syscall must be disabled when it is used to create a
thread because it cannot work reliably in its current state.
- the system to intercept calls to the syscall page must be made more
generic to be used at least by arm user and x86_64 user.
- It would be good to limit the changes in the CPU emulation code to
handle the TLS. For example, on MIPS, the TLS register must not be
stored in the CPU state. Same for ARM.

Fabrice.
